More Girls Born in the Wake of Disasters

Stress during these trying times of disaster might be the underlying cause, sister. What is clear from the data and statistics is that more girl babies were born right after disasters like the March 2011 earthquake in Japan and even after the stock market crash of 2008 in the US. What’s less clear is whether the stress related to these types of events causes mothers to miscarry more males or whether fewer males are conceived indicating a reduction in Y chromosome sperm for men. Some believe the reason in either case may be evolutionary since boys are more likely to be premature and suffer problems associated with low birth weight than girls. This means nature selects and in other words it may be more beneficial for the mother to give birth to a girl during and following times of disaster, natural or financial. Now if only there was a way to predict the disasters so to be better able to coordinate shopping for the correct baby accouterments.
